連詞可以分為并列和從屬連詞兩類,下面就兩類連詞分別加以講解。
漫談一:并列連詞
并列連詞根據(jù)它的意義和用途,可分為并列、轉(zhuǎn)折、因果和選擇四種。
一、表示并列關(guān)系的連詞有:and, both…and…, not only… but also…和neither…nor…等
1、and:和,并且
A:基本用法:
“and”表示 “和”、“并且”的意思,用來連接對(duì)等關(guān)系的字和字,片語和片語,句子和句子。
I enjoy basketball , football and table tennis.
The weather becomes colder and colder.
B:特別用法:
祁使句后連接and,有條件句作用,此時(shí)and=if you…,you’ll…
Go straight on, and you’ll see the library.==If you go straight on, you will see the library.
2、both…and…既…也…,(兩者)都…
A、both…and…構(gòu)成的詞組作主語時(shí),謂語動(dòng)詞用復(fù)數(shù)。
Both Jim and Kate are from England.
B、both…and…否定句表示部分否定。
You can’t speak both German and English.
Both my father and my mother aren’t doctors.
3、neither…nor…:既不…也不…
neither…nor…連接兩個(gè)并列主語時(shí),謂語動(dòng)詞靠近哪個(gè)主語就與哪個(gè)主語保持 “人稱”和 “數(shù)”的一致,即采取就近原則。
Neither I nor he has seen the play before.
4、not only…but also…:不但…而且…
not only…but also…連接兩個(gè)主語后的謂語動(dòng)詞也遵循就近原則。
Not only the mother but also the children are ill.
